## 开场 您的ER20夹头套装从原材料棒料开始加工,而非目录中的标准毛坯。我们根据您的图纸加工每一个锥面、槽口和螺纹。发货前,每支夹头均经过三坐标测量机和测试心轴检验。您收到的零件夹持精准、同心运转,并在生产负载下保持公差。

  • 公差:锥面和内孔±0.005 mm
  • 表面粗糙度:夹持面Ra 0.4 µm
  • 交期:标准规格7–12天,定制规格15天
  • 无起订量——可订购1件或1,000件
  • 每批次均附材质证明和完整检测报告

## 规格参数 我们在五轴CNC车削中心和磨床上加工ER20夹头。每件零件均经过相同工艺流程:车削、磨削、开槽、热处理、精磨、检验。每一批次均检测硬度,而非每百件抽检一件。

参数数值
材料65Mn弹簧钢、20CrMnTi或9Cr18不锈钢(按您的规格)
硬度HRC 45–52(弹簧钢),HRC 50–55(合金钢)
锥角每侧8°,磨削至±0.002 mm
内孔公差H6或H7,视图纸要求而定
槽宽0.8–1.2 mm,线切割加工
表面粗糙度锥面Ra 0.4 µm,本体Ra 0.8 µm
同心度距端部3 mm处TIR ≤0.005 mm
热处理真空淬火+回火,无氧化皮
工艺CNC车削、无心磨削、线切割、热处理
批量1至5,000件,小批量无换线费用
检测三坐标测量机、硬度计、光学投影仪、测试心轴

定制CNC弹簧夹头ER50重型高精度 中国制造

我们不会省略磨削工序。许多工厂在车床上车出锥面就交差了事,这会导致刀具尖端跳动超差。我们在热处理后进行磨削,因此即使金属在淬硬过程中发生变形,锥面仍能保持精准。

## 客户将图纸交给我们的三大理由 1. 批次可追溯的质量。 每支夹头都有炉号和批次编码。如果六个月后发现任何问题,我们可以调出记录,告诉您确切的炉次、热处理周期和检验员。无需猜测。

2. 每批次附检测报告。 您无需仅凭信任。每批货物均附带尺寸检测报告,包含锥角、内孔尺寸、槽宽和同心度的实际测量值。硬度读数按每件列出,而非按批次平均值。

3. 同一工厂完成CNC加工+冲压+弹簧+散热器。 您的夹头组件可能需要冲压锁紧螺母、用于松开机构的压缩弹簧,或用于电主轴的马达散热器。我们在同一厂区内全部完成。一张采购订单、一套质量体系、一个交货日期。无需协调三家供应商。

  • CNC铣削主轴 — 三轴和五轴加工中心的刀具夹持,尤其适用于频繁换刀的场合
  • 自动车床 — 走心式和滑动头机床的棒料送进和工件夹持
  • 机器人换刀系统 — 自动化单元中的快速释放刀具
  • PCB钻孔和铣边 — 高速主轴,跳动直接影响孔位精度
  • 医疗器械制造 — 需要TIR小于5 µm的小直径切削刀具
  • 航空航天夹具作业 — 检测过程中夹持定位销和定位特征

如果您正在制造主轴或改造机床,请将图纸发给我们。我们已生产过20 mm至20 mm刀柄刀具的夹头,以及非标毛坯的定制内孔尺寸。

## 客户订购前常问的问题 问:起订量是多少? 答:无起订量。我们接受单件原型订单,也可批量至数千件。仅当零件需要特殊成型刀具或夹具时才收取刀具费用。标准ER20规格无刀具费用。

问:如何保证公差和质量? 答:我们在热处理后磨削锥面和内孔,而非热处理前。每支夹头均在三坐标测量机上测量并在心轴上测试。检测报告显示实际数值,而非仅通过/不通过的盖章。零件若超出规格,绝不发货。

问:定制夹头的交期是多久? 答:标准ER20规格7–10天发货。定制内孔直径或特殊槽型需12–15天,含热处理和磨削。紧急订单可分批交货,首批零件5天内发出。

问:能否提供材质证明? 答:可以。每批次附带原材料钢厂证明、含实际硬度曲线的热处理报告,以及尺寸检测报告。所有文件均为英文,可追溯至批次编码。

## 发送您的图纸 我们在12小时内报价,而非等到下周。请发送您的图纸并注明数量、材料和所需硬度。您将获得确定的价格,无隐藏刀具费或换线费。
